[R-pkg-devel] help with ASAN

[Steven Scott]

I'm trying to build an ASAN enabled version of my R library to help debug
errors found by CRAN on my last submission.  I'm tantalizingly close, but
need some help figuring out what's wrong with my configuration.

I'm using a docker container that I think contains a version of R built
with the right options.  I launch the docker container as so:

docker run --cap-add SYS_PTRACE -e PASSWORD=<redacted> --rm -p 8787:8787 -v
/home/steve/code/BOOM:/home/steve/code/BOOM -it rocker/r-devel-ubsan-clang
/bin/bash

In this container I have added a ~/.R/Makevars file with the following
content:
CC= clang -std=c99 -fsanitize=address -fno-omit-frame-pointer
CXX= clang++ -std=c++11 -fsanitize=address -fno-omit-frame-pointer
CXX11= clang++ -std=c++11 -fsanitize=address -fno-omit-frame-pointer
FC = gfortran -fsanitize=address

When I build my package I get:
(... expected compiler output truncated except for final compile and link
step ... )
clang++ -std=c++11 -fsanitize=address -fno-omit-frame-pointer -std=gnu++11
-I"/usr/share/R/include" -DNDEBUG -I`/usr/lib/R/bin/Rscript -e
